Quonset Soils

Soil Map Unit Description from the RI Soil Survey Report

QoA—Quonset gravelly sandy loam, 0 to 3 percent slopes.

Link to Official Soil Series Description for Quonset Soils

This nearly level, excessively drained soil is on terraces and outwash plains. Areas are irregular in shape and range mostly from 5 to 75 acres.

Typically the surface layer is very dark gray gravelly sandy loam about 3 inches thick. The subsoil is dark yellowish brown and light olive brown gravelly loamy sand. The substratum is dark gray very gravelly sand to a depth of 60 inches or more.

Included with this soil in mapping are small areas of excessively drained Windsor and Hinckley soils, some what excessively drained Merrimac soils, well drained Agawam soils, and moderately well drained Sudbury soils. Included areas make up about 10 percent of this map unit

The permeability of this soil is moderately rapid or rapid in the surface layer and subsoil and very rapid in the substratum. Available water capacity is low, and runoff is slow. The soil is extremely acid through strongly acid in the surface layer and subsoil and strongly acid through slightly acid in the substratum.

This soil is suitable for community development. Onsite septic systems need careful design and installation to prevent pollution of ground water. Slopes of excavated areas are commonly unstable. Lawn grasses, shallow-rooted trees, and shrubs require watering in summer.

This soil is suited to trees, but most areas are cleared and used for farming. The main limitation for woodland is droughtiness; seedling mortality is high during dry summers.

This soil is suited to cultivated crops. Irrigation is needed. Cover crops and the return of crop residue to the soil help to maintain tilth and organic mailer content.

This soil is suited to woodland wildlife habitat and openland wildlife habitat. It is too dry to provide wetland wildlife habitat. Capability subclass IIIs; woodland group 5s.

QoC—Quonset gravelly sandy loam, rolling.

Link to Official Soil Series Description for Quonset Soils

This excessively drained soil is on terraces, outwash plains, kames, and eskers. Slopes range from 3 to 15 percent. Areas are irregular in shape and range mostly from 2 to 20 acres.

Typically the surface layer is very dark gray gravelly sandy loam about 3 inches thick. The subsoil is dark yellowish brown and light olive brown gravelly loamy sand 13 inches thick. The substratum is dark gray very gravelly sand to a depth of 60 inches or more.

Included with this soil in mapping are small areas of excessively drained Windsor and Hinckley soils, some what excessively drained Merrimac soils, well drained Agawam soils, and moderately well drained Sudbury soils. Included areas make up about 10 percent of this map unit.

The permeability of this soil is moderately rapid or rapid in the surface layer and subsoil and very rapid in the substratum. Available water capacity is low and runoff is slow. The soil is extremely acid through strongly acid in the surface layer and subsoil and strongly acid through slightly acid in the substratum.

Most areas of the soil are in woodland or are cleared and used for pasture.

This soil is suitable for community development. Onsite septic systems need careful design and installation to prevent pollution of ground water. Slopes of excavated areas are commonly unstable. Lawn grasses, shallow-rooted trees, and shrubs require watering in summer. The use of straw bale sediment barriers and quickly establishing plant cover help to control erosion during construction.

This soil is suited to farming. The hazard of erosion is moderate, and irrigation is needed. The use of cover crops, diversions, and stripcropping and the return of crop residue to the soil help to control erosion and maintain tilth and organic matter content.

This soil is suited to woodland wildlife habitat and openland wildlife habitat. It is too dry to provide wetland wildlife habitat. Capability subclass IVs; woodland group 5s.
